APPARATUS FOR WORKING AND IVIOLDING DOUGl-l.

SPECIFICATION forming part of Letters Patent 110.614,79?, dated November22, 1898- I Application iiled August 20, 1898. Serial No. 689,091. (Nomodel.)

To all whom, t may concern:

Be it known that I, CHRISTOPHER DoBsoN, a subject of the Queen of GreatBritain and Ireland, residing at Kirkham, in the county of Lancaster,England, have invented Improvements in Apparatus for W'orking and 'AMolding Dough, of which the following is a specification.

This invention has reference to apparatus whereby a gyratory orcircumrotary motion canbe imparted to dough, so that it will becomerubbed or rolled and thereby worked up and molded in a similar manner tothat in which pieces of dough have heretofore been worked up and moldedby hand for the purpose of making loaves, tea-cakes, buns, and the like.For this purpose the apparatus is provided with one or moreendwise-movable presses, to which a gyratory or circumrotary motion isimparted and which or each of which is adapted to engage with and imparta similar motion to a piece of dough placedV between it and a table orboard.

Apparatus to act in the manner described can be constructed in variousforms.

Figures 1 and 2 of the accompanying illustrative drawings are elevationsat right angles to one another; and Fig. 3 is a horizontal section onthe line c o: of Fig. 1, showing one construction of apparatus accordingto this invention.

In this example there are three tables or boards 1, the center one ofwhich is arranged below a movable holder 2, provided with a number ofpiston-like or cylindrical pressers 3, having perforated bottoms 3, sothat a number of pieces of dough can be simultaneously operated upon.Each table may be formed with a number of shallow concave depressions 1to increase the biteor hold on the lower side of the pieces of doughbeing operated upon. The pressers 3 may conveniently be made ofsheetmetal, and the perforated bottoms 3 may be of concave or domeshape, as shown. The boards l are mounted to slide upon longitudinalbearers l on the fixed bed 5 of the framing 5 of the apparatus and aremoved endwise by tappets or projections G, carried by two endless chainsor bands 6, which are arranged to pass around pulleys 7 7, that can berotated by a handwheel (not shown) fixed upon the shaft 7 of one ofthem.

By using three boards, as shown, molded pieces of dough can be removedfrom the forward one and fresh pieces of dough be placed upon therearward one while the pieces of dough on the middle one are beingoperated upon, thus admitting of a large output from the apparatus.

The holder 2 consists of a wooden board formed with a number of circularholes to receive the pressers 3. These pressers are capable of beingslid by hand a greater or less distance up or down in the circular holesin the holder 2 to suit the sizes of the loaves, buns, or the like to bemade, the small perforation in the concave or dome-shaped bottoms 3fLserving to allow dry flour to work through upon the dough in process ofbeing molded. The pressers 3 may be weighted in any suitable way. It maybe by loose shot placed in them, and which by rolling` about will assistthe iiour to pass through the perforated bottoms 3. The holder 2 issuspended by pins 7 7 from a pair of crank-disks 3 S, Xed upon verticalspindles 9 9, which are Asuitably rotated for the purpose of impartingthe desired gyratory or circumrotary motion to the holder and thepressers 3 carried thereby. For this purpose in the example shown thereis conveniently mounted at the upper part of the framework of themachine a driving-shaft 10, provided with fast and loose pulleys 10 10b,driven by a belt from a suitable source of power. At one end of thespindle 10 is a bevel gear-wheel 11, that engages with another bevelgear-wheel 12, lthe sleeve 12 of which rotates within a bracket13,1'ixed to the framework 5. Passin through the gear-wheel 12 androtated thereby is the vertical spindle 9, which is provided with a longkey or feather 9X, that can slide freely in a corresponding keyway inthe gear-wheel 12 and enables the said spindle to be raised or lowered.The vertical spindle 9 is arranged to slide vertically in abearing-bracket 13 and in the example shown is provided withv a pulley14, by which it can be rotated from a similar pulley 14; on the spindle9 through an endless belt 15. If desired, the spindle 9 might be drivenfrom the shaft 10 through gearing like the spindle 9. The verticalspindles 9 9 and `their attached parts are carried by means ot' brackets16 16, upon which rest collars formed on the said spindles, the saidbrackets being xed to a frame or support 17.

In order that the vertical distance between the concave bottoms 3ct anddepressions 1n on the pressers and board, respectively, can be varied tosuit requirement, the holder 2 is made vertically adjustable. For thispurpose the frame or support 17 carrying it is made capable of beingraised and lowered and is formed at its upper part of angle-iron for thepurpose of being guided in its vertical movements by the framing 5 ofthe apparatus. It is held in the raised position by means ofbalance-weights 1S, adapted to counterbalance the frame 17 and the partscarried thereby, the said weights being suspended by chains 19, thatpass around guide-pulleys 2O from the lower part of the frame or support17 ,which is provided with a suitable bar or rail 2l, by which theframe,with holder, pressers, and attached parts, can be forced down tothe requiredextent by a foot of the operator. The lower end of the frame17 consists of rods connected together by cross-stays 17u.

The amount of gyratory movement imparted to the holder 2 and pressers 3can, if desired, be varied to suit dierent requirements by forming thedisks 8 8 with several holes 8 of varying ecoentricity, and into eitherof which the crank-pins 7 7 can be placed.

As will be seen, the construction of the apparatus hereinbeforedescribed is such that when the pressers 3 are lowered upon pieces ofdough placed upon the board 1 below the pressers and the verticalspindles are rotated a gyratory movement will be imparted to the holder2 and pressers 3 carried thereby, so that each piece of dough will berubbed or rolled between the board and the presserabove it, whereby thesaid piece of dough will become worked up in a manner similar to thateffected by hand-working and will be gradually brought to the requiredrounded form.

The apparatus is specially advantageous for producing the top and bottompieces of dough required for making loaves of bread of the kind known ascottage loaves.

The shape of each presser may be variously modified, provided it iscapable of rising and falling, and will upon being operated as describedrub or roll a piece of dough placed between it and the board, so as towork the same after the manner of hand-worked dough.

What I claim isl. In an apparatus for working dough, the combination oftwo opposing parts between which a piece of dough can be held, means forimparting a gyratory motion to one of said parts, one of said partsprovided with one or more dough-holding recesses,and the opposite partprovided with one or more piston-like dough-pressers, substantially asdescribed.

2. Apparatus for working and molding dough, comprising a table or board,a holder arranged opposite said table or board, one or more presserscarried by said holder, and means for imparting a gyatory motion to saidholder.

3. Apparatus for working and molding dough, comprising a table or board,a holder arranged opposite said table, or board, one or more pressersmounted in said holder and formed with a recessed lower side, and meansfor imparting a gyratory motion to said holder.
